I concur with the glyph analysis, which also matches Alan Kaye's
discussion of Jawi in Daniels and Bright.
However, I also think it is quite clear that U+06AC ARABIC LETTER KAF
WITH DOT ABOVE is the one that was intentionally encoded for the Jawi
ga character. This has been marked as an "old Malay" letter ever since
The error would seem, rather, to be in choosing an inappropriate
representative glyph for the charts, and in the shaping class
assigned to the character in ArabicShaping.txt:
06A9; OPEN KAF; D; GAF
06AB; KAF WITH RING; D; GAF
06AC; KAF WITH DOT ABOVE; D; KAF
06AD; KAF WITH 3 DOTS ABOVE; D; KAF
06AE; KAF WITH 3 DOTS BELOW; D; KAF
06AF; GAF; D; GAF
I'd say, as for the Pashto Kaf with ring, that the appropriate shaping
class should be "GAF", not "KAF", in this file.
Let's pass this by other Arabist specialists in the UTC before
taking further action.
